【摘要】 介绍了微波暗室内雷达散射截面（ＲＣＳ）自动测量系统。主要包括同步转角信号的Ａ／Ｄ转换，ＲＣＳ值的同步采集与处理以及转台的自动控制等部分。该系统具有１／３６度的定位精度和２．５ｍＶ的回波电压分辨率，系统误差小于１ｄＢ，适用于ＲＣＳ、天线方向性图及电磁兼容（ＥＭＣ）等测量。更多还原

【Abstract】 An automatic meaurement system for radar cross section (RCS), in microwave anechonic chamber,which is composed of A/D transformation of synchronous angulersignal of rotator,data acquisition and processing of RCS and automatic control of rotator,is presented. This system with a resolution of 1/36 degree in anguler signal and 2.5mV in RCS signal can be used in the measurement of RCS. Electromagnetic Compatibility (EMC) and antenna pattern.更多还原
